Hi,
I am a 36-year-old bisexual male. I am sexually active, and receive oral sex (without a condom) somewhat frequently.
I noticed a few years ago that I have about 7 or 8 white pimple-looking bumps on the left side of my scrotum. Believing them to be whiteheads, I excised the largest one with my fingernails. My scrotum bled a bit, and the contents of the bump came out. It was not pus as I expected from a whitehead, but much more pliable (yet fibrous) white tissue. The strange thing is, it grew back in just a few days. These bumps are itchy, but they don't seem to bother me too much unless I see them. I have tried to "pop" them several times over the years, but they grow right back to exactly what they looked like before. I have had a complete array of STD test since I first noticed them--and all negative. I'm getting more and more worried.
Thanks in advance for your attention.
